intermesbing of the vrivet heads and reribs or eogs 5 on wlinks 5l! of an endless chain' which in this construction is substituted' for the belt 3 and plates 11- o the first form.

' rlfhe links 5b are hinged together end to end,

the 'hinges proper projecting inwardly in the form of ribs or cogs composed of lugs 5c end 5d on the meeting ends of each pair of adjacent links, see Fig. 4c. These lugs are connected by loins 1G. The :ribs or coge formed by the hinges are adapted to inter- 'mesh with grooves l1 in the rim or tire of the wheel, i, thus providing a positive driving connection between the chain, co1nposed of the bolts 5b, and the Wheel, which positive connection is necessary when the Wheel is to be driven by the chain, as in motor trucks. The flanges on the shoes eXy clude dirt and mud. from the chain and also keep said chain, in proper position on the Wheel, es in the construction illustrated in Figs. i. to 3 inclusive. The bottom surface of each of the shoes may be made convex, as et 12, Fig. 5, to prevent skidding and also reduce their Weight. i

Having thus described my invention,

- what l( claim as new and desire to secure by 3:3

Letters Fatent of the United States is:

' 1'. lin a structure of "the character dey scribed the combination with a rotary memthe shoe member, rigid plates fastened to the outer surface of said band and adapted to engage the shoe member, and intermeshmg menus on said plates and shoes whereby they I are detachably interlocked.

3.1i). a structure of Vthe character described the combination with a rotary nuern-I ber, of nn endless shoe member loosely surrounding` the same,y and comprising shoes hii'igcd end to end, and having recesses in their inner faces, an endless band interposed between the .rotary member andthe shoe member, and rigid plates riveted to the vouter surface of said band, the heads of the rivets protruding on the outer faces. of said plates and adapted to engage the recesses 1n the shoes. 1

In testimony whereof I have signed my name to this speciiication in the presence of two attesting witnesses.
